This example demonstrates the column chooser in the
RadGridView. The column chooser is a form which can be used to easily customize
the columns to be shown in the RadGridView.
Anytime a column is removed from the RadGridView, it can be
found in the Column Chooser. Columns can be dragged and dropped from the RadGridView to the Column
Chooser and vice versa to set the desired configuration of columns to be shown in the grid.
